what would the slope intercept equation of the line shown below
Answers
Answer:
y = -2x - 4.
Step-by-step explanation:
The points marked are (-2,0) and (0,-4).
The slope of line = (-4-0) / (0- -2)
= -4/2 = -2.
The y-intercept is at y = -4,
so the equation required is y = -2x - 4.
Answer:
y = - 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line
m = [tex]\frac{-4-0}{0+2}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2
The line crosses the y- axis at (0, - 4) ⇒ c = - 4
y = - 2x - 4 ← equation of line

Paulette’s brother gave her his DVD collection of 25 movies when he went to college. She started buying DVDs each month after that. The line-of-best fit which models the relationship between the number of DVDs Paulette has in her collection (n ) and the time since her brother went to college in months (m ) is given in the box.
n=1.8m+25
To the nearest number of DVDs, what is the approximate number of DVDs in Paulette’s collection after 14 months?
Answers
after 14 months, paulette has 75 DVDs in her collection
The approximate number of DVDs in Paulette’s collection after 14 months is 75 DVDs.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
let the collection of DVDs ne n and the time spend is m.
and, the Equation for the situation is
n = 1.8 m + 25
Now, the number of DVDs in collection after 14 months is
= 1.8 (14)+ 25
= 50.2
So, the total number of DVDs are
= 50 + 25
= 75

What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
There are 1 2/5 groups of 1 2/3 inches.
Now,
Since, There are 1 2/5 groups of 1 2/3 inches.
Hence, The number of inches = 1 2/5 × 1 2/3
= 7/5 × 5/3
= 7/3 inches.
Thus, There are 2 1/3 inches in 1 2/5 groups of 1 2/3 inches.

HELP ME ASAP IF U CAN!!! a baker needs sugar syrup that is 40% sugar how many gallons of water shoud he add to 5 gallons of 70% sugar syrup to make the 40% syrup. WILL MAKE BRAINLYEST
Answers
Answer:
15/4
Step-by-step explanation:
Equation: 40(5+x)=70*5+0x
Solve:
200+40x=350
40x=150
x = 15/4
15/4 gallons is the answer.
3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept.
Let x represent the amount of water in galloons needed to be added to make 40% sugar. Hence:
40% of (x + 5) = 70% of 5
0.4x + 2 = 0.7 * 5
0.4x = 1.5
x = 3.75
Therefore 3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup

The perimeter of a rectangle is 208 inches. The ratio
of its length to its width is 5:3. What are the
dimensions of this rectangle?
A. 60 in by 44 in
B. 65 in by 39 in
C. 68 in by 36 in
D. 72 in by 32 in
Answers
Answer:
The dimensions of this rectangle are 65 in by 39 in ⇒ B
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The perimeter of the rectangle = 2(length + width)
∵ The perimeter of a rectangle is 208 inches
∴ 208 = 2(length + width)
→ Divide both sides by 2
∴ 104 = length + width
∵ The ratio of its length to its width is 5: 3
∴ The sum of the ratios = 5 + 3 = 8
→ By using the ratio method
→ length : width : length + width
→ 5 : 3 : 8
→ x : y : 104
→ By using cross multiplication
∵ x × 8 = 5 × 104
∴ 8x = 520
→ Divide both sides by 8
∴ x = 65
∵ y × 8 = 3 × 104
∴ 8y = 312
→ Divide both sides by 8
∴ y = 39
∵ x and y represents the length and the width of the rectangle
∴ The length = 65 inches
∴ The width = 39 inches
∴ The dimensions of this rectangle are 65 in by 39 in
